The Water Infinity bottoms are standard Infinity bottoms that have been coloured with a Rune guardian. To do this, players must use their infinity bottoms on the Water altar with their rune guardian either following them or in their inventory. Once coloured, they are untradeable. Colouring infinity robes is cosmetic and will not change their stat bonuses. In order to remove the colouring, players may use the robes on their rune guardian.
